I've gotten Osceleton set up & am receiving messages in Max. However, I'm having a tough time understanding how the coordinate system works.
I can see l_hand moving in a reasonable way if I look at that point in isolation. However, looking at the coordinates for l_hand versus head, I'm not sure how to interpret what I'm seeing. I would expect that having someone move their left hand from hip level to above their head should give a set of values where the Y coordinate for l_hand crosses the Y coordinate for head. (In other words, if Y for l_hand is less than for head at hip level, it should be greater when the hand is above the head. Likewise, if Y for l_hand is more than for head at hip level, it should be lower than for head when the hand is above the head.)
That doesn't seem to happen; I get a range of values for l_hand, but that range doesn't seem to have anything to do with where head is.
Am I missing something? Are the coordinates for a point relative in some way rather than absolute points within the field of view?
